read Information from a web

Hi, I got this code to run all the information from a page but when I run it on matlab I get errors. The code is:

"descripcion" : "exito",

"estado" : 200,

"datos" = "https://opendata.aemet.es/opendata/sh/79adac19",

"metadatos" : "https://opendata.aemet.es/opendata/sh/b3aa9d28"

in the first link I got all the information I want how can I get it??

Where did you get that code? It's not MATLAB code. Just putting that into a script will not cause it to "read" or "run" "all the information from a page". You probably need to call webread() or something. Please attach your script (m-file) if you have one.

I just got this from the page and do not know how to do it to be able to read it

Hi,

From my understanding, you're looking to retrieve data from a web service, and you've shared a JSON snippet that contains a URL under the ‘datos’ key, which seems to be the endpoint where the data can be accessed.

To retrieve data from a web service using MATLAB, you can utilize the "webread" function.

Please refer to the documentation links below:

www.mathworks.com/help/matlab/ref/webread.html

www.mathworks.com/help/matlab/ref/weboptions.html

Below is an example MATLAB code to accomplish this:

% Defined the URL from the "datos" field 
datosUrl = 'https://opendata.aemet.es/opendata/sh/79adac19'; 

% If an API key is required, setup using weboptions 
% Replace 'your_api_key_here' with the actual API key if needed 
options = weboptions('HeaderFields', {'api_key', 'your_api_key_here'}); 

%If an API key is not required, you can simplify the options setup 
%options = weboptions(); 

% Retrieve the data from the URL 
try 
    % Use webread to get the data 
    data = webread(datosUrl, options); 
    
    % Display or process the data 
    disp(data); 
catch ME 
    % Handle any errors that may occur 
    fprintf('Error retrieving data: %s\n', ME.message); 
end 

I hope this helps!
